Marine Algae Starver Phosphate Remover for Marine Reef & Fish tanks 500ml

A coral-safe liquid phosphate remover, reducing the phosphates to such a low level that it starves the algae, causing it to perish. Controls the algae, leaving you with an algae free aquarium. Safe for anemones, clams, shrimp & soft corals. Add 5ml to 100 litres of water every 2 to 3 days if phosphate levels are greater than 1ppm. Do not add to an acid tank. Always raise pH to over 7.0 before treatment commences. Algae Starver should be used at 5ml to 50lt until algae subsides. Once you have completed the treatment you should take a water sample to your aquarium professional to be tested for phosphates. Once you have achieved a phosphate level of less than 2ppm, add a maintenance dose of 5ml to 100lt every 2 weeks.
